axapta - 如何获取 FormReferenceGroupControl 的值

Question

在D365表单开发中，我喜欢获取输入到表单控件中的值，表单控件是一个带有Party引用字段的表单引用组控件。

如何获取输入到控件的值？

尝试过：

ReferenceGroup.controlNum(i).valueStr();

FieldBinding 与 filterValue

两者也不行。

它应该像在 FormReferenceGroupControl 对象上调用 value() 方法以获取底层引用值(int64) 一样简单，该值是底层数据源的 RecId。例如：

FormReferenceGroupControl referenceGroupControl;

referenceGroupControl = element.control(element.controlId(formControlStr(ReferenceGroupTestingForm, ReviewHeaderInfo_CustomsRepRefGroup))) as FormReferenceGroupControl;

referenceGroupControl.value(); //returns the RecId of the DirPerson table displayed.

要获取替换给用户的Display 值，而不是存储在数据库中的基础 RecId 值，请执行以下操作：

FormReferenceGroupControl referenceGroupControl;

referenceGroupControl = element.control(element.controlId(formControlStr(ReferenceGroupTestingForm, ReviewHeaderInfo_CustomsRepRefGroup))) as FormReferenceGroupControl;

//this gets the string control that is substituted in for the reference value/recid and displayed to the user. This is the second underlined control in the picture below. This control is determined by the ReferenceGroupControl property "Replacement Field Group" 
//Could be a different type of control than a String control depending on your scenario
FormStringControl subStringControl = referenceGroupControl.controlNum(1) as FormStringControl;

subStringControl.text(); //for string controls, text will contain the display value

最后要注意的一件事是，我相信可以通过操作数据源对象而不是 formcontrol 对象来获取值。我过去在搜索谷歌搜索结果时看到过这样的解决方案。如果我再次遇到他们，我会更新答案
